The online Gallery is a new kind of modification using valves source engine to construct a virtual gallery that you can walk around with your friends or family. The gallery upon completion will include the ability to change the actual images ingame with those of your own therefor making every gallery you create unique and giving you the option to name your gallery and then publish it on the internet for you and your friends to download and share, You will still be able to connect to the gallery and walk around it online, yet the images you see will be different to what others see therefor you can have groups of familes and friends walking around the same gallery but actually seeing there own implemented photographs,
